Roof Replacement Calculator
Preliminary estimate
Enter your address and we'll measure the roof and price the replacement — usually within seconds.
This is a starting range, not a bid. Every figure carries its own source, and anything the sources can't agree on goes to a human before it reaches you.
How it's measured
01
Permit records
A reroof permit often declares the roof area in squares — a real measurement, taken by a roofer who stood on it. It also tells us the roof's age.
02
Aerial imagery
Solar imaging reads each roof plane's ground area and pitch. Same footprint is 16% more material at 10/12 than 6/12 — pitch matters as much as area.
03
Street photos
A vision model reads stories, material, layers, and penetrations at the eave edge — the details that move the estimate.
This is a preliminary range, not a bid. Every figure carries the source it came from, and anything the sources can't agree on goes to a human before it reaches you. Real numbers come after a walkthrough.
